One end of the moving contact piece 11 abuts against one end of the static contact piece 9;

[0027] The fixed component 7 includes a connecting plate 701. The outer surface of the upper shell 301 is provided with the connecting plate 701. A groove is formed on the outer surface of the lower shell 302, and a mounting hole is formed on the inner surface of the groove. The connecting plate 701 is fitted and installed inside the groove. A sliding groove is formed on the outer surface of the connecting plate 701, and a guiding rod 702 is arranged inside the sliding groove. A slider 703 is slidably connected to the outer surface of the guiding rod 702. The sliders 703 are set to be two and symmetrically distributed. A third spring 704 is installed between the two sliders 703. The third spring 704 is sleeved on the outer surface of the guiding rod 702. A limiting block 705 is installed at one end of the slider 703 away from the third spring 704. One end of the limiting block 705 penetrates through the connecting plate 701 and is fitted and installed inside the mounting hole;

[0028] Through the coordinated use of the connecting plate 701, the guiding rod 702, the slider 703, the third spring 704 and the limiting block 705, the clamping structure is replaced, thereby avoiding the wear of the clamping part between the upper shell 301 and the lower shell 302 after repeated use, and then affecting the use of the upper shell 301 and the lower shell 302, achieving a better practical effect;

[0029] A placement groove 401 and a limiting groove 402 are formed on the outer surface of the lock core 4. A connecting column 403 is arranged on the lower surface of the lock core 4. A notch 601 is formed on the outer surface of the lock tongue 6. A guide pin 10 is fitted and installed inside the placement groove 401. The connecting column 403 is fitted and installed inside the notch 601. A dust-proof component 12 is installed on the outer surface of the lock core 4;

[0030] A threaded hole is formed on the outer surface of the lock shell 1, and a screw 13 is threadedly connected inside the threaded hole. One end of the screw 13 is fitted and installed inside the limiting groove 402;

[0031] A connecting seat 101 is arranged on the outer surface of the lock shell 1. A limiting hole is formed on the outer surface of the connecting seat 101. A limiting column 30201 is arranged on the outer surface of the lower shell 302. The limiting column 30201 is fitted and installed inside the limiting hole.

[0032] The dust-proof component 12 includes a protective shell 1201. The upper surface of the protective shell 1201 is hinged with a cover plate 1202 through a pin rod. A through hole 1203 is formed on the upper surface of the protective shell 1201. The protective shell 1201 is installed on the outer surface of the lock core 4;

[0033] By providing the protective shell 1201 and the cover plate 1202, the lock core 4 can be covered, preventing dust from entering the inside of the lock core 4 and affecting the service life of the lock core 4, achieving a better protection effect.

[0034] During use, first install the lock housing 1 on the outer surface of the battery box, and connect the static contact piece 9 to the external connecting wire. When unlocking is required, rotate the cover plate 1202 so that the cover plate 1202 rotates axially around the pin rod. After the through port 1203 is exposed, insert the key into the through port 1203, and then insert the key into the interior of the lock core 4. By rotating the key counterclockwise, the lock core 4 rotates axially within the lock housing 1. During the rotation of the lock core 4, the lock tongue 6 is driven to move, causing the lock tongue 6 to retract into the interior of the lock housing 1. At the same time, the guide pin 10 disengages from the interior of the placement groove 401 and abuts against the outer surface of the lock core 4. During this process, the guide pin 10 drives the moving contact piece 11 to move within the switch housing 3, causing the moving contact piece 11 to cancel contact with the static contact piece 9. When the lock tongue 6 is completely retracted into the interior of the lock housing 1, the unlocking of the lock body is completed. When locking is required, rotate the key clockwise. When the moving contact piece 11 or the static contact piece 9 needs to be replaced, rotate the bolt 2 to loosen the bolt 2 and cancel the fixed installation between the lock housing 1 and the switch housing 3. Then remove the switch housing 3. By inwardly squeezing the two sliders 703, the two sliders 703 slide towards the closer ends within the sliding grooves, and at the same time, the limit block 705 gradually disengages from the interior of the installation hole. When the two sliders 703 are completely in contact, the limit block 705 completely disengages from the installation hole. Then, the upper housing 301 can be pulled upward to separate the upper housing 301 from the lower housing 302, and thus the moving contact piece 11 and the static contact piece 9 inside the upper housing 301 and the lower housing 302 can be replaced. After replacement, place the upper housing 301 directly above the lower housing 302 and push the upper housing 301 downward to close the upper housing 301 and the lower housing 302. When the limit block 705 abuts against the upper surface of the lower housing 302, by inwardly squeezing the two sliders 703, the two sliders 703 slide towards the closer ends within the sliding grooves, and at the same time, the third spring 704 gradually contracts. When the limit block 705 abuts against the inner surface of the groove, the upper housing 301 can be continuously pushed downward to complete the closing of the upper housing 301 and the lower housing 302. After closing, cancel the force on the slider 703, causing the third spring 704 to recover its elasticity and push the slider 703 to reset, so that the limit block 705 is fitted into the interior of the installation hole to complete the fixed installation between the upper housing 301 and the lower housing 302. Through the coordinated use of the connecting plate 701, the guide rod 702, the slider 703, the third spring 704, and the limit block 705, the clamping structure is replaced, thereby avoiding wear at the clamping joints of the upper housing 301 and the lower housing 302 after repeated use, which may affect the use of the upper housing 301 and the lower housing 302, and achieving a better practical effect.

[0035] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, according to the content of this specification, many modifications and variations can be made.
